One of the most important nitrogen compounds is ammonia (NH3), which can be produced in the so-called Haber-Bosch process, in which nitrogen is reacted with hydrogen. The colorless ammonia gas with a pungent smell can be easily liquefied into a nitrogen fertilizer. In fact, about 80 percent...
The destruction of either hydrogen sulphide or carbon disulphide by active nitrogen appears to be minimal at some temperature in the range 200–250 °C. Both reactions yield large amounts of polymer.It is postulated that the main reactions involve destruction of the reactant as it acts as a ...
In present tokamaks nitrogen seeding is used to reduce the power load onto the divertor tiles. Some fraction of the seeded nitrogen reacts with hydrogen to form ammonia. The behaviour of ammonia in ASDEX Upgrade is studied by mass spectrometry. Injection without plasma shows strong absorption at ...
Removal of one electron from •NO creates the nitrosonium cation (NO+) which has the ability to react with nucleophilic centers, producing nitroso compounds. Nitrosyl halides are liberated when •NO reacts with fluorine, chlorine, or bromine. The half-life, solubility, and biological reactivity...
the unique micro-/meso-porous structures and the high surface area-to-volume ratios in the material can lead to higher density of catalytic active sites and favorable structures that enable fast transport of reactants, ions, and electrons14,34,35,36,47. Additionally, the N-HPCNPs-900 possess...
and the direct combination of nitrogen with hydrogen. In the first approach, air or any other uncombined mixture of oxygen and nitrogen is heated to a very high temperature, and a small portion of the mixture reacts to form the gas nitric oxide. Thenitric oxideis then chemicallyconvertedto ...
The azides, like the halogen compounds, readily react with other substances by displacement of the so-called azide group and yield many kinds of compounds. Nitrogen forms many thousands of organic compounds. Most of the known varieties may be regarded as derived from ammonia, hydrogen cyanide, ...
Additionally automating the distillation step complicates things even further, so much so that many researchers have sought effective alternatives to the Kjeldahl method. One is on-line UV photo-oxidation in the presence of an oxidant such as hydrogen peroxide or sodium peroxydisulfate (the APHA ...
That’s because in the summer months, heat and sunlight react with the precursor gases in the atmosphere, like nitrogen dioxide, creating a toxic cocktail. FromScience News As Cahn explained, “You can’t control nitrogen without controlling your irrigation water.” ...
The Haber-Bosch process directly synthesizes ammonia from nitrogen and hydrogen and is the most economical nitrogen-fixation process known. About 1909 the German chemist Fritz Haber ascertained that nitrogen from the air could be combined with hydrogen under extremely high pressures and moderately high...
